如何重构这个switch语句？ [英] How to refactor this switch statement?

问题描述

string liquidClass = string.Empty;

switch (cmbLiquidClass.Text)
{
    case "LiquidClass1":
        liquidClass = Settings.Default.LiquidClass1;
        break;
    case "LiquidClass2":
        liquidClass = Settings.Default.LiquidClass2;
        break;
    case "LiquidClass3":
        liquidClass = Settings.Default.LiquidClass3;
        break;
    case "LiquidClass4":
        liquidClass = Settings.Default.LiquidClass4;
        break;
    case "LiquidClass5":
        liquidClass = Settings.Default.LiquidClass5;
        break;
    case "LiquidClass6":
        liquidClass = Settings.Default.LiquidClass6;
        break;
    case "LiquidClass7":
        liquidClass = Settings.Default.LiquidClass7;
        break;
    case "LiquidClass8":
        liquidClass = Settings.Default.LiquidClass8;
        break;
    case "LiquidClass9":
        liquidClass = Settings.Default.LiquidClass9;
        break;
}

尝试将当前类的内容导入局部变量。我不能使用字典，因为字符串的工作方式（表现得像值类型）。有没有办法重构这个，所以它不需要这么多行来找到所选的液体类？

Trying to get in to a local variable the contents of the current class. I can't use a dictionary because of the way strings work (behaving like value types). Is there any way to refactor this so that it doesn't require this many lines to find the chosen liquid class?

推荐答案

可以使用 Settings.Default （使用.Net 4.0测试）的一部分的索引器：

You can use the indexer that is part of Settings.Default (tested with .Net 4.0):

var liquidClass = Settings.Default[cmbLiquidClass.Text].ToString();
